Hello, about a week ago seemingly out of nowhere my audio became distorted ("fuzzy", "crackling"), it's an intermittent problem. All sources seem to be affected: Windows system sounds, streaming music and radio, i-tunes, flash video. It seems to be an internal PC issue rather than speakers or amplifier because the music playback also slows down ("stutters:) when this happens, also happens when headphones are plugged directly into the PC tower. Audio controller is SoundMAX Integrated Digital Audio. The driver was updated within the last year with no issues then.

Any ideas on how to proceed? I want to keep this old beast functioning for my kids. Dell Dimension 2400, XP Home SP3, Pentium 4 2.66 Ghz, 1.5 GB RAM.

Thanks

Try reinstalling your audio driver. As an integrated component for the Dell dimension 2400, you may be looking to install a soundcard if capable.

PROBLEM SOLVED: My IDE ATA/ATAPI controllers for the primary and secondary IDE drive channels had been switched to PIO (slower) transfer mode instead of DMA, not exactly sure what all this means but it solved the problem, apparently this can happen from an optical drive trying to play a damaged CD disc? Here is a link to the fix: forum.digital-digest.com/f105/how-check-your-dma-status-reset-if-necessary-61905.html

Hat tip to Bleeping Computer tech gringo_pr for the fix!

Thanks!

Thanks for the feedback, more on DMA/PIO:

DMA reverts to PIO Windows Problem Solver - http://winhlp.com/node/10

IDE ATA and ATAPI disks use PIO mode after multiple time-out or CRC errors occur - http://support.microsoft.com/kb/817472

Happy computing :).
